The body of 22-year-old Savanna LaFontaine-Greywind was found Sunday evening by kayakers. She was located in the Red River, which borders North Dakota and Minnesota, "heavily wrapped in plastic and duct tape" and stuck to a log.

Three days earlier, police found a baby in the apartment of LaFontaine-Greywind’s neighbors, 32-year-old William Henry Hoehn and a 38-year-old Brooke Lynn Crews. Police believe the newborn girl belonged to LaFontaine-Greywind.

According to the court documents obtained by PEOPLE, Hoehn told police he found Crews cleaning up blood in the bathroom upon coming home August 19. Crews was also holding a newborn girl. She allegedly told him, “This is our baby, this is our family.”

An ABC affiliate reports that Crews claimed she "took advantage" of LaFontaine-Greywind to take away her unborn child. But, she also said that the victim handed over her baby voluntarily after Crews taught her to self-induce birth by breaking her own water.

That claim contradicted what Hoehn told police. He said he removed garbage bags full of bloody towels and his bloody shoe from their home.

Both suspects have been charged with conspiracy to commit murder, conspiracy to commit kidnapping and providing false information to law enforcement. They are being held without bond.
